Title:
DEVICE AND METHOD FOR THE QUALITATIVE AND/OR QUANTITATIVE ANALYSIS OF CONSTITUENTS IN LIQUIDS, ESPECIALLY IN DRINKS AND PROCESS LIQUIDS
Document Type and Number:
WIPO Patent Application WO2005047873
Kind Code:
A3
Abstract:
The invention relates to a method and a device for the qualitative and/or quantitative analysis of constituents in liquids, especially in process liquids and/or in alcoholic and non-alcoholic drinks in open containers or in closable or closed containers or barrels subjected to a pressure that is higher than, equal to, or lower than the atmospheric pressure, said container or barrel comprising at least one container wall, lid or bottom region and/or a closure that can be pierced. The analysis is carried out by means of a flow measuring cell containing an ATR crystal and integrated into an infrared spectrometer. Said measuring method can also be used to analyse liquids in containers with a high internal pressure, under real conditions. The invention also relates to a flow measuring cell.
